Abstract: FIELD: construction. 
     SUBSTANCE: invention relates to construction, namely to facades of energy-efficient buildings, and can be used in construction of energy-active and environmentally safe residential and public buildings with high degree of heat protection. Design of dynamic energy-saving facade with variable properties comprises wall from traditional wall materials (monolithic concrete, brick, blocks from cellular concrete, wooden bar, etc.) with layer of effective insulation, for example, from mineral wool covered with wind-hydro-protective membrane, and external dynamic layer consisting of installed with possibility of synchronous rotation around their parallel in one plane of vertical axes of triangular prisms, which side faces are able to be arranged in one plane or parallel planes and have the following properties: first face in form of vacuumized insulating glass window with thickness of 6–8 mm with vacuum of 10 -3 –10 -4  mm Hg and with selective coating on glass inner surface with emissivity ε=0.10–0.20, connected to two other faces, having on the inner surfaces a selective coating with an absorption coefficient α=0.80–0.95 and emissivity ε=0.10–0.20; second face has coating on outer side with reflection coefficient ρ=0.85–0.90 and the third face on the outer side has a film solar battery. Top plugs of triangular prisms come out with their hollow branch pipes into horizontally sealed box with perpendicularly located channel to it with influx valve, which extends to inner face of wall. Bottom plugs of triangular prisms have bushings installed in mounting holes of horizontal box and having on end a driven gear, which interacts through drive gear with mechanism of prism turning. One of the elements of the prisms turning mechanism is a horizontally arranged shaft connected through a reduction gear to a step motor. Engine can be located in right or left post both vertically and horizontally. Shaft turns at a certain angle (or turns at the required number of revolutions) and is delayed in the required position to allow setting the prism faces having similar properties in the same plane. Control unit controls the operation of the drive. Depending on weather and preset conditions and time in accordance with program it sets prisms in preset position and determines time of stationary condition of prisms. Dynamic energy-saving facade operates in an automated mode and comprises an engine control unit, a charging device and an accumulator which are in sealed compact housings placed in the right or left side post. Inside the side post there are special fasteners for this purpose. Engine and charger control is performed so as to optimize engine operation in terms of power parameters, increasing its efficiency and resource, reducing power consumption, providing fast charge of the accumulator and its long-term storage. 
     EFFECT: electronics provides accelerated charging of accumulator from solar batteries or by another method during 3–4 hours.
